Abstract: A scanning optical apparatus has a light source for emitting a light beam, and a deflector such as rotatable polygonal mirror (7) having a plurality of mirror surfaces (7A, B) for deflecting the light beam emitted from the light source (3). Each mirror surface (7A, B) of the rotatable polygonal mirror (7) has a pair of reflecting surfaces (7A, B) inclined toward the center axis of rotation of the polygonal mirror (7) and orthogonal to each other. A fixed reflecting mirror (9) is arranged in opposed relationship with one of the pair of reflecting surfaces so that the light beam deflected by the deflector is reflected to be returned to the deflector again.

Abstract: A method of optical transmission comprises steps of generating a light signal, controlling a wavelength of the light signal in accordance with a correcting signal, and modulating an intensity of the light signal supplies from a light source (1) to generate an output light signal in accordance with a modulating signal. The wavelength change of the light signal generated by the light source (1) coincides with the wavelength change which occurs during the modulating step, so that the wavelength change is cancelled in the output light signal. An optical transmitter used in the method comprises a light source (1) which generates a light signal, a correcting signal generating circuit (3) which supplies the light source (1) with a correcting signal for changing the wavelength of the light signal generated by the light source(1) and an optical modulator (2) which modulates an intensity of the light signal supplied from the light source (1) to generate an output light signal in accordance with a modulating signal.

Abstract: The multilayer structure consists of several individual layers, the individual layers having a thickness of less than 100 nm and the individual layer structure can be virtually compensated by heating to operating temperature. Uniform electrically conductive multicomponent material is deposited on an electrically conductive substrate by a PCVD process. A plasma, for example a glow discharge plasma, a high frequency plasma or a microwave plasma, is produced in a reaction space. The plasma is moved periodically to and fro. Starting materials for the individual components of the multicomponent material are added to a flowing gas phase. In order to obtain multicomponent material of the desired composition, the flowing gas phase is divided into at least two flowing gas phases, each of which contains only starting material for an individual component of the multicomponent material. The individual gas phases are fed in succession to the plasma. The deposited multicomponent material is optionally subjected to a heat treatment. <IMAGE>

Abstract: A frame synchronization stabilizer for stabilizing frame synchronization of received data (S in ) has a generation circuit (10) for generating a reference pattern which is the same as a predetermined frame synchronization pattern contained in data being transmitted. The stabilizer further has a comparison circuit (11) or comparing, bit by bit, a data pattern in a synchronization pattern area of each frame of the received data (S in ) with the reference pattern from the generation circuit (10). The comparison circuit (11) outputs a mismatch pulse (S mis ) each time when a mismatch bit is detected by the comparison, and outputs a match pulse (S math ) each time when it is detected that the data pattern is fully matched with the reference pattern. The number of the mismatch pulses from the comparison circuit (11) is counted by a first counter (12). The first counter outputs (12) an out-of frame detection signal (S out ) when a counted value exceeds a particular value and is reset based upon the match pulse (S math ) from the comparison circuit (11).

Abstract: An aircraft radar altimeter includes a programmed microcontroller (22) which permits effective simultaneous tracking of at least two targets such that, for example, both ground and obstacles on the ground can be simultaneously tracked, thus avoiding crashes when the aircraft is operating at very low altitudes. The microcontroller (22) is operatively coupled to the radar transmitter (29) and to the receiver (34, 36, 40) so that information relating to a first target can be stored away while a search and track operation is run on a second target. The information concerning a detected second target is likewise stored away and the microcontroller permits alternate tracking of the two targets with the stored information being used as the basis for establishing an initial position for a target when tracking of that target is resumed.

Abstract: A controllable frequency generator exhibits a pulse source (OSC), followed by a digital frequency divider (TL), and an interposed gate circuit (TR). The output pulse sequence fA of the frequency divider (TL) passes to a converter feeding the load and to an input of a pulse rate multiplier (PRM), the output of which is connected to the control input of the gate circuit (TL). Each output pulse in each case inhibits the gate circuit for the duration of one clock pulse of the pulse source. A computer (R) supplies, on the one hand, a control word corresponding to the desired divider factor to the control input (STL) of the frequency divider (TL) and, on the other hand, a control word effecting the suppression of certain pulses to the control input (SPRM) of the pulse rate multiplier (PRM). The frequency of the output pulse sequence fA is selected in such a manner that each halfwave of the load current is composed of the same integral number of pulses. <IMAGE>

Abstract: PLL synthesizer circuitry comprises a phase comparator 3 which produces output signals φR and φP on the basis of a reference signal fr, output from a reference frequency divider 2, and a comparison signal fp output from a comparison frequency divider 4; the output signals φR and φP are negatively fed back to the comparison frequency divider 4 through a charge pump 5, a low-pass filter 6 and a voltage control oscillator 7, and a lock detection circuit 8 outputs a lock signal LD when in a locked state. When an output signal SVCO of the voltage control oscillator 7 coincides with a set frequency, when the lock detection circuit 8 does not output the lock signal LD, a reset circuit 15 outputs a reset signal PC to the reference frequency divider 2 and to the comparison frequency divider 4, and the reset signal PC brings the phase of the reference signal fr into conformity with the phase of the comparison signal fp. 
     Such circuitry can shorten lock-up time without reducing unacceptably a time constant of a low-pass filter of the circuitry.

Abstract: A method and apparatus utilizing automated semantic pattern recognition whereby a user of a manual enters a query regarding information in the text of the manual and the invention displays the locations in which information responsive to the query is located. The present invention includes a computer that stores a data structure representing the natural language text of a manual, the structure being a tree structure having nodes, wherein each node represents information from associated locations of the text. The nodes at higher levels of the tree represent general categories of information. Nodes at succeedingly lower levels of the tree represent succeedingly more specific categorical subsets of the general categories of information represented at the higher levels by ancestors of the lower level nodes. The query is formatted into a query data structure that is similar in format to the node structure representing the text. The query data structure is compared to each node in the tree. If the degree of similarity between the query and the node exceeds a predetermined threshold value after taking into account the degree of similarity between the ancestors of the node and the query, then the locations associated with the node are displayed on a video monitor as locations containing information responsive to the query.
